FIELD OF THE DISCLOSURE

This disclosure, in general, relates to a mounting system for mountingauxiliary devices to firearms, methods of using such mounting systems,methods of manufacturing such mounting systems.

BACKGROUND

As demand has increased for firearms, so too has demand for auxiliarydevices, such as laser sights, infrared light sources, and visible lightspectrum sources. Demand for such auxiliary devices is particularlystrong in military, civilian defense, and police applications. Manyoperations occur at night or in low light conditions, rendering weaponmounted lighting systems desirable. But, such systems tend to sufferfrom deficiencies in power limitations, activation methodologies, andthe obstruction of a firearm user's forward view.

As such, improved auxiliary devices and associated mounting systemswould be desirable.

In an example, the head device can also include a plurality oflaser light sources. In a particular example, the visible light sourcesare disposed to project forward from the head device on opposite sidesof a vertical axis of symmetry of the head device. Two of the pluralityof infrared light sources can be disposed on opposite sides of thevertical axis of symmetry. For example, a first of the plurality ofinfrared light sources is disposed on a first side of the axis ofsymmetry and a second of the plurality of infrared light sources isdisposed on the other side of the vertical axis of symmetry. The headdevice can further include a mounting connector for connecting thedevice to a mounting system of a firearm. In an example, the mountingsystem is a rail system and the mounting connector of the head device isattached to a rail of the rail system.

In an exemplary embodiment illustrated in FIG. 1 and FIG. 2, a firearm100 includes a body 102 having a firearm handle 104 and a trigger 110.The body 102 can interface with a cartridge 108 to supply ammunition.The body 102 can attached to a barrel 112. The distal end of the barrel112 forms a front of the firearm 100. A stock 106 can be attached to thebody 102 at a rear of the firearm.

Along the barrel 112 and forward of the stock 106, firearm handle 104,and trigger 110 is disposed a rail mounting system 114, forming part ofa handguard. The rail mounting system 114 can include a plurality ofrails to which auxiliary devices are optionally attached and can includea control rail to which a control handle 116 is attached. Optionally, ahead device 118 can be attached to the rail mounting system 114, and thehead device 118 can be controlled by the control handle 116 through therail mounting system 114, through a wire interface 120, or through aunitary or solid electrical connector formed or connected between thehead device 118 and the handle 116.

In a particular example illustrated in FIG. 2, the head device 118attaches to the rail mounting system 114 using a rail mounting connector226. On opposite sides of a vertical axis of symmetry, the head device118 includes visible light sources 222. In addition, the head device 118can include a plurality of other light sources, such as infrared lightsources, laser light sources, or any combination thereof. Additionalaccessory devices can be further attached to the head, such as cameras,additional lights, laser pointers, or Taser devices.

In an example, a head device includes a housing, main light assembly,infrared (IR) light assemblies, a powered cradle, internal wiring, afixed connector, a floating connector, an insulating substance, or aback plate. For example, as illustrated in FIG. 3, a head device 300includes a housing 302 and a back plate 304 to the housing 302. Thehousing 302 can define cavities 306 at the top and on opposite sides ofa vertical axis of symmetry to house visible light sources 308. Thehousing 302 can further house light sources of different spectrumsdisposed on opposite sides of the vertical axis of symmetry. Forexample, the housing 302 can include light sources, such as infrared,ultraviolet, red, green, blue, multi-color, or blue laser light sources,or a combination thereof. For example, infrared light sources 310 can bedisposed on opposite sides of the axis of symmetry. In another example,red, green, blue, or multi-color visible spectrum light sources 312 canbe disposed on opposite sides of the axis of symmetry within the housing302. In a further example, ultraviolet light sources can be disposed onopposite sides of the axis of symmetry. In an additional example,sensors can be disposed in addition to or in place of one or more of thelight sources and optionally on either or both sides of the axis ofsymmetry within the housing. An example sensor can include a thermalsensor, such as an infrared sensor.

The housing 302 defines a central bore 318 through which the barrelextends or through which a bullet may pass. The housing 302 can furtherdefine a connector 314 to assist with connecting the head device 300 toa rail mounting system. In an example, the connector 314 is disposed ata top of the head device 300 and defines a structure similar to a railto which the head device 300 is to be mounted. A complementary connectorconnecting a rail of the rail mounting system to the rail connector 314can provide interconnection between the rail mounting system and thehead device 300. Alternatively, the connector 314 can be fixed railmounting device or structure. In an example, the connector 314 is afixed rail connector having a complementary Picatinny configuration or aKeyMod configuration.

The head device 300 can further include a second connector 316 tooptionally connect the head device 300 to the rail mounting system.Alternatively, the connector 316 can be floating connector or can allowconnection of additional devices to the head device 300. In a particularexample, the second connector 316 is disposed near the bottom of thehead device 300.

In an example, the head device 300 can be formed of a heat resistantmaterial, such as a high temperature plastic polymer or metal. Forexample, the housing 302 can be made from thermal molded plastic, castor milled metal, or other appropriate materials.

FIG. 4 and FIG. 5 include exploded view illustrations of the head device300. A lens 424, spacer 422, and visible light source 420 can bedisposed within the cavity 306 defined by the housing 302. Inparticular, the visible light source 420 can be a drop-in manufacturedcomponent. The light source 420 can have the capacity to generate lightwith various colors, intensities, and strobe patterns, for example, ascontrolled by an external controller, such as a handle controller.

A back plate 304 can be connected to the housing 302 to form awatertight sealed housing. A waterproof electronic connector 426 canconnect to the back plate 304 of the head device 300. In particularexample, when viewed from the rear, the electronic connector 426 isdisposed on the left side of the head device 300.

As illustrated in FIG. 4 and FIG. 5, the connector 314 is a fixedconnector for mounting the head device 300 to a rail mounting system428. In an alternative example, an adjustable connector can be providedto attach the head device 300 to the rail mounting system 428.

An adjustable connector 316 can be used to provide further support andconnect the head device 300 to the rail mounting system 428.Alternatively, the connector and interface 316 can connect the headdevice 300 to additional devices. In an example, an additional deviceincludes a Taser, laser, camera, night vision, solar charging assembly,weights for recoil or rise compensation, or any combination thereof

In an additional example, the head device 300 can include an interfaceto attach additional equipment to the connector of the head device 300.For example, the connector 316 can be adjusted to connect other devicesto a bottom of the head device. The connector 316 can include anelectronic interface for controlling the additional device.Alternatively, a split cable can be provided that includes an interfacefor the electrical connector 426 and connections for the additionaldevice.

In a particular example, a power cradle can be defined under andprotected by plate 440. The power cradle can include a floatingconnector and can further define an internal well and a track whichallow the floating connector to move in and out of the housing. Inanother example, the powered cradle includes a powered connector toreceive an auxiliary device, such as a camera, thermal camera, laser,Taser, thermal sensor, sound sensor, tracking device delivery system,weights for recoil and rise compensation, night vision, a solar chargingassembly or a combination thereof. In an example, a plurality (e.g.,two, three, or four) metal cradle tabs connect the wiring harness of theinternal wiring to the powered cradle at cradle slots, which can be usedto control an auxiliary device attached to the power cradle.

In an example, internal wiring includes circuitry, connections, andshielded or unshielded wire, which can be used to deliver electricalpower to the various components of the device. The internal wiring canbe configured in a Y-shaped harness, delivering power from the powerconnector multi controller (e.g., the electrical connector 426 or aninternal power source) to the powered cradle, the main light assemblies308, and the IR light assemblies 310. The internal wiring can be securedto the components with locking connectors at each of the nodes.

In a further example, the head device 300 can be filled with a heatresistant or electrically insulative medium. For example, an electricaland thermal insulating substance in the form of a gel, paste, epoxy, orother viscous medium can be used to cover the electrical connections andcomponents interior to the housing 302. A rear gasket and back plate 304can attach to the beveled rear opening of the housing 302, and can befixed in place, for example, by back plate screws through back platescrew holes.

A power connector hole at the lower portion of the back plate houses thefemale power connector (e.g., electrical connector 426), which can besealed by a power connector O-ring, a power connector nut, and powerconnector sealant. In an example, the female power connector is a fourpost, four ground connector, or a similarly configure connector. In aparticular example, the female power connector can be attached to anexternal multi-controller and power source which powers and facilitatesvarious modes of operation for the main light assemblies, IR lightassemblies, and powered cradle of the head device 300.

As illustrated in FIG. 6 and FIG. 7, at the rear, the head device 300connects to the rail mounting system 428. In an example, a fixed railmounting connector 314 can connect the top of the head device 300 to atop rail of the rail mounting system 428. An adjustable or floatingconnector 316 can connect a bottom rail of the rail mounting system 428to the head device 300. Alternatively, the floating connector 316 can bereplaced with an additional auxiliary device.

As further illustrate in FIG. 6 and FIG. 7, the waterproof multi-wireconnector 426 can be provided at the rear of the head device 300. Theelectrical multi-wire connector 426 can connect to a control handle.

When viewed from the front as illustrated in FIG. 9, the head device 300includes a plurality of visible light devices 308 disposed on oppositesides of a vertical axis of symmetry 950. In particular, a first lightsource 308 can be disposed on a first side of the axis of symmetry 950and another visible light source 308 can be disposed on an opposite sideof the axis of symmetry 950.

In addition, the plurality of infrared light sources 310 can be disposedwithin the housing 302. For example, a set of infrared light sources canbe disposed on a first side of the axis of symmetry 950, and another setof the infrared (IR) light sources can be disposed at opposite side ofthe axis of symmetry 950. In an example, the sets of IR light sourcescan be assemblies of pairs of infrared light emitting diodes and can beCree LED, incandescent, or Xenon assemblies or any other forms.

Further, other light sources 312 can be disposed within the housing. Inparticular examples, opposing sets of light sources 312 can be disposedon opposite sides of the axis of symmetry 950. In particular, lightsources 312 of the same type can be disposed on opposite sides of theaxis of symmetry 950. Optionally, the housing 302 can include a powersupply.

FIG. 8, FIG. 10, and FIG. 11 include illustrations of different views ofthe head device 300. For example, FIG. 8 includes a side view of thehead device 300 in which the housing 302 connects to connectors 314 or316 and the light sources 308 extend from a top of the head device 300in a forward direction.

In a further example, FIG. 12A and FIG. 12B illustrate a rail mountingsystem 1200. The rail mounting system 1200 includes a plurality ofpowered rails 1202 and a control rail 1204. A support 1210 supports therails 1202 and 1204 and defines a central bore 1208 through which abarrel of a firearm can extend.

As illustrated, the rail mounting system 1200 includes three poweredrails 1202. In general, the rail mounting system 1200 can include atleast one powered rail 1202, such as at least two powered rails 1202, atleast three powered rails 1202, or four or more powered rails 1202.Generally, the mounting system 1200 does not include greater than 10powered rails.

The powered rails 1202 can have a Picatinny configuration. In anotherexample, the powered rails can have a KeyMod™ configuration. In anadditional example, the powered rails can have an M4 Rail™, LiteRail™,RIS II, or Omega Rail™ configuration, or a combination thereof. In afurther example, the powered rails 1202 can have a propriety mountingconfiguration. While the illustrated embodiments of the rail mountingsystem 1200 illustrate each of the powered rails 1202 as providing thesame mounting configuration, each of the powered rails 1202 can have adifferent mounting configuration.

The control rail 1204 can have a mounting configuration similar to themounting configuration of the powered rails 1202. In another example,the control rail 1204 can have a Picatinny configuration. In a furtherexample, the controller 1204 can have a KeyMod configuration. In anadditional example, the control rail can have an M4 Rail™, LiteRail™ RISII, or Omega Rail™ configuration, or a combination thereof.Alternatively, the control rail 1204 can have a proprietary mountingconfiguration.

The control rail 1204 can provide power to one or more of the pluralityof powered rails 1202. In particular, a handle including a power supplyor another power supply interfacing with the control rail 1204 canprovide power through electrical conduits to each of the plurality ofpowered rails 1202. In a particular example, the control interface ofthe control rail 1204 can allow for selectively providing power toselect individual powered rails 1202 without providing power to theother powered rails. As such, one or more of the powered rails 1202 canoperate and be provided power independently.

Further, the system allows for different voltages in different wavepatterns to be provided to select individual powered rails 1202. Forexample, a power supply interfacing with the control rail 1204 canprovide a first voltage or first waveform to one of the power rails 1202operating a different voltage or a different waveform than another ofthe powered rails 1202. In particular, depending on the power supply,voltages of 1.5 V, 3V, 6V or 9V can be provided to select rails of theplurality of powered rails. Further, different waveforms can be providedto a powered rail, such as a constant, a square waveform, a sinusoidalwaveform, a saw tooth waveform, or a combination thereof

In a particular example, the electrical conduits can extend from thecontrol rail 1204 to the individual powered rails 1202 through a rimstructure 1206 that extends around the circumference of the support1210. For example, the rim 1206 can extend along a leading-edge or aback edge of the support 1210. In an alternative example, the rimstructure 1206 can extend around the support 1210 at a position betweenthe front and back of the support 1210.

When viewed in cross-section, as illustrated in FIG. 13, the railmounting system 1200 provides for the powered rails 1202 and controlrail 1204 to be distributed around the circumference of the support1210. The support 1210 defines the central bore 1208 through which abarrel of a firearm can extend. As illustrated, the rails 1202 or 1204are distributed evenly around the circumference of the support 1210. Inan alternative example, the rails 1202 or 1204 can be distributedunevenly around the circumference of the support 1210.

As illustrated, the control rail 1204 resides in a bottom position ofthe support 1210, while three powered rails 1202 are distributed withoffsets of 90° from each other around the circumference of the support1210. The rim 1206, which can house the electrical conduits from acontrol rail 1204 to the powered rails 1202, can extend around thecircumference of the housing 1204 either at a front edge of the support1210 or a back edge of the housing support 1210.

While FIG. 12A and FIG. 12B illustrate the rail mounting system 1200 asa single piece system, the rail mounting system can be supplied is amulti-part system, as illustrated in FIG. 14. For example, a top piece1402 can be attached to a bottom piece 1404 to connect around a barrelof a firearm. Alternatively, two side pieces can be attached aroundopposite sides of a barrel to form the rail mounting system. Inparticular, a multi-piece rail mounting system finds use for front sightmounted weapons in which the front sight mounting limits access to thebarrel from the distal end of the barrel.

FIG. 15 illustrates an exemplary powered rail 1500. The powered rail1500 includes coupling positions 1502 at which an auxiliary device canbe coupled. In the Picatinny configuration illustrated, the attachmentsite can include one or more teeth 1504 and a lower surface 1506. Alongthe side of the rails can extend a ridge 1508 to assist with theattachment of an auxiliary device to the rail system. A couplerassociated with the auxiliary device can extend around the ridge 1508,securing the auxiliary device to the ridge and preventing side-to-sideand vertical motion.

Below the ridge 1508 is a side surface 1510 disposed on each side of therail 1500. At each of the attachment positions, the powered rail 1500can include power access points 1512. The power access points supplypower or access to ground. In a particular example, access points 1510to a common electrical conduit can be provided on one side 1510 of thepowered rail 1500, and access points to a separate electrical conduit,for example, a power supply or ground, can be provided on an oppositeside of the powered rail 1500.

When not in use, a strip of insulator 1514 can be supplied to coverunused access points 1510. Optionally, the strip 1514 can include raisednodules 1516 that fit within the access points 1512.

When viewed in cross-section, as illustrated in FIG. 16, the poweredrail 1602 can include a first electrical conduit 1604 extending along afirst side of the rail 1602 and a second electrical conduit 1608extending along a second side of the rail 1602. An access point 1606 canbe provided to access the rail 1604. The access point 1610 can havesimilar configurations to the access point 1606. For example, the accesspoints can be a hole, a clip disposed within a hole and connected to therespective rail or a solid conductor electrically connected to therespective rail. An exemplary hole or opening defining the access point1606 or 1610 can be circular in shape. In another example, the hole oropening can be ovular, rectangular, square, or polygonal. In a furtherexample, the hole or opening can taper as it extends toward the conduit1604 or 1608. In an additional example, a compliant material or membranecan be disposed in the hole or opening, which opens to expose theconduit 1604 or 1608 in response to insertion of a pin or contact.

In a particular example, the access points 1606 or 1610 can be openingsproviding access to the rails 1604 or 1608 respectively. The openingscan have a characteristic diameter defined as the square root of thecross-sectional area divided by pi (i.e., sqrt(A/pi)) of 0.15 mm to 2mm, such as 0.25 mm to 1.5 mm or 0.5 mm to 1.25 mm. The openings 1606 or1610 can have a depth of 0.15 mm to 6 mm, such as 0.15 mm to 3 mm or 0.5mm to 2 mm. The openings 1606 or 1610, can have a circularcross-section. In another example, the openings 1606 or 1610 can have across-section of a polygonal shape, such as a triangle, a rectangle, ahexagon, or an octagon. In particular, the shape and diameter can beconfigured to limit water incursion into the opening based on surfacetension at an air/water interface at the opening. Such exclusion ofwater can prevent unwanted current generation along the firearm andlimit corrosion.

The control rail can include a plurality of attachment points. At theattachment points, the control rail can also include a control interfaceto provide electrical interaction between the control rail and thepowered rails. For example, as illustrated in FIG. 17, the control railcan include a plurality of attachment points 1702. In the illustratedexample, the attachment points 1702 can include at least one tooth 1704and a depressed portion 1706. At one or more of the attachment points1702, the control rail 1700 can include a control interface 1712. Thecontrol interface 1712 can include one or more contacts or electricalcontacts. In an example, the contacts can be electrical contact pads. Inanother example, the contacts can be clips for receiving pins. Inanother example, the contacts can be access points similarly to theaccess points described above and optionally having similar dimensionsand cross-section.

For example, the control interface 1702 can include a plurality ofaccess points having a characteristic diameter of 0.15 mm to 2 mm, suchas 0.25 mm to 1.5 mm or 0.5 mm to 1.25 mm. In a further example, thecontrol interface access points can have a depth of 0.15 mm to 6 mm,such as 0.15 mm to 3 mm or 0.5 mm to 2 mm. Further, the controlinterface access points can have a circular cross-section. In anotherexample, the control interface access points can have a cross-section ofa polygonal shape, such as a triangle, a rectangle, a hexagon, or anoctagon. In particular, the shape and diameter can be configured tolimit water incursion into the opening based on surface tension at anair/water interface at the opening. Such exclusion of water can preventunwanted current generation along the firearm and limit corrosion.

In an example, the interface 1712 can provide electrical interactionwith a plurality of electrical conduits 1716 extending through thecontrol rail 1700. For example, the interface 1712 is illustrated asbeing disposed on a top surface of the rail 1700 and the plurality ofelectrical contacts 1716 extend horizontally along the rail 1700 underthe surface 1706. Alternatively, the control interface 1712 can bedisposed on the top surface 1704.

Optionally, the control rail 1700 has a ridge 1708 around which thecontrol attachments can be secured. Under the ridge 1708, the controlrail 1700 includes a side surface 1710. Optionally, along the sidesurface 1710 at one or more of the attachment points 1702 are additionalaccess points 1714. Such access points 1714 can be used to provide powerto additional accessories attached to the control rail instead of thepowered rails. Alternatively, the access points 1714 can provide accessto a common electrical conduit. In an example, the access points 1714provide connection to a select conduit 1718 extending along or under thesurface of side surface 1710. For example, the conduit 1718 can extendin a manner similar to the rails 1604 or 1608 illustrated in FIG. 16.

In an alternative example, the control interface 1712 can be provided onone or both of the side surfaces of the control rail 1700. In such anexample, multiple access points can be provided at each of one or moreof the attachment positions 1702 along the side surfaces 1710 thecontrol rail 1700.

FIG. 18 illustrates an exemplary configuration for the electricalconduits. In an example, an electrical conduit 1802 can provide a commonelectrical connection between the control rail and each of the poweredrails. A set of additional electrical conduits 1804 can provide selectelectrical access to individual powered rails and optionally, thecontrol rail. In an example, the common electrical conduit can be aground conduit. In another example, the common electrical conduit canprovide power and each of the individual electrical conduits 1804 canprovide access to the ground when connected through a control circuitry.In particular, a rail mounting system can be molded or cast around theconduits.

A power supply or control device can be connected to the control railand electrically access the control interface. In a particular example,a handle that includes a power supply and control circuitry to controlthe control interface can be connected to the control rail. For example,as illustrated in FIG. 19A and FIG. 19B, a handle 1900 includes a grip1902 that can interface with a hand and includes a rail interface 1904to engage and attached to a control rail of a rail mounting system. Inparticular, the handle electrical interface 1906 is disposed as part ofthe rail mounting or attachment interface 1904. In an example, thehandle control interface 1906 can include contact pads or pins, such asPogo pins, to interact with the control interface of the rail mountingsystem. As illustrated, the handle control interface 1906 is positionedto interact with a control interface mounted on the surface of a controlrail. Alternatively, the handle control interface 1906 can be disposedon one or both sides of the rail attachment interface 1904 interfacewith a side mounted control interface of a rail mounting system.Alternatively, as illustrated in FIG. 47, a handle control interface4700 can be attached to a front of the grip. A grip connector 4702 canbe connected to a rail interface 4706. The rail interface 4706 caninclude pins 4708 to control rails of the rail system and optionally caninclude pins 4710 to access the common or power connectors to the sideof the control rail.

An exemplary handle 1900 includes an electronic interface, such as amode select button 1908 and an activation button 1910. Optionally, thebuttons (1908 and 1910) can be counter sunk In another example, anadditional activation button can be included on an opposite side of thehandle 1900 as the mode select button 1908. In operation, the modeselect button 1908 can be toggled between different modes providingpower to select rails depending on the functionality of the mode selectbutton 1908, and the activation button 1910 can be depressed toimplement the mode selected using the mode select button 1908.Optionally, the handle 1900 can have an additional activation buttonpositioned on the same side of the handle 1900 as the mode select button1908 or on the opposite side of the handle of the mode select button1908. In particular, the additional activation button can activate adifferent device than the activation button 1910. For example, theactivation button 1910 can activate light devices based on the modeselected through the mode select button 1908, whereas the additionalactivation button can activate a different type of device or a devicehaving significant consequences, such as a Taser device, for example, inresponse to selection of a Taser mode using the mode select button 1908.An exemplary handle can further include a front multi-pin electricalinterface 1912 to provide a wired connection to a head mounted devicethat includes a plurality of light sources. In an example, the buttonscan be counter sunk to prevent accidental activation.

In addition, the handle 1900 can include a programming or recharginginterface 1914 that can access an external power supply or acomputational device. For example, the computational device can be usedto program the modes selectable using the mode select button 1908. Inanother example, the electrical interface 1914 can provide forrecharging a power supply of the handle 1900. For example, the interface1914 can allow for interaction with a battery, line power, solar power,or other power supply, or any combination thereof, to recharge orprovide power to the handle 1900.

In a particular example, a lower surface of the handle 1902 configuredto interface with the palm of the hand is disposed at an angle arelative to a horizontal plane of the rail to which the handle isattached. A select range of angles also provides for desirablepositioning of the hand and activation of different muscle groups withinthe arm and can be selected to provide improved muscle control, recoilcontrol, or reduce fatigue. In an example, the angle a is in a range of5° to 60°, such as a range of 10° to 60°, a range of 10° to 45°, a rangeof 15° to 35°, or a range of 18° to 30°.

As illustrated in FIG. 20, the handle can extend down along a verticalaxis of symmetry 2010. For example, a rail mounting system 2002 includesa plurality of powered rails 2006 and a control rail 2008. In theillustrated example, the control rail 2008 extends downward along thevertical axis of symmetry 2010. The handle 2004 can extend to have acenter of gravity and a grip surface disposed below along the axis ofsymmetry 2010. Alternatively, the grip interface of the handle 2004 canhave a center line disposed at an angular offset from the verticallyextending axis of symmetry 2010. For example, the lower interface orgrip interface of the handle 2004 can have a center axis that is at anangle y relative to the vertically extending axis of symmetry 2010 in arange of 0° to 45°, such as a range of 0° to 30°, a range of 5° to 25°,a range of 5° to 18°, ora range of 5° to 15°.

In a particular example, the handle provides multiple contact surfaceswhich provide for improved control of the firearm using the leading handand arm. For example, as illustrated in FIG. 21, FIG. 22, and FIG. 23, ahandle 2100 includes a handle body 2102 with an upper surface 2104 toattach to a rail mounting system. In addition, the body 2102 can providea lower contact surface 2106, side contact surfaces 2108 and 2116, anindex finger contact surface 2112, and a thumb contact surface 2118. Inaddition, the handle body 2102 can include a contact surface 2110 tocontact a side of the hand and can include curved upper contact surfaces2120 to contact the tip of fingers or the hand at the base of the thumb.In a particular example, a ridge 2114 separates the contact surface 2112for the index finger from the contact surfaces 2106, 2108, and 2116 tocontact the palm of the hand.

The thumb contact 2118 can provide an upper surface onto which the thumbrests and can extend out from the body 2102 to define a protected recessthat prevents the thumb from being readily struck from the side. Thethumb contact 2118 can include a lower surface 2126 onto which a side ofthe thumb or the tip of the thumb rests and can optionally define a stopsurface 2124 to be contacted by the tip of the thumb to signalpositioning of the thumb or hand or to prevent access to the thumb froma forward position. In a particular example, the thumb contact 2118 canbe placed at an angle δ relative to a horizontal place of the rail in arange of 0° to 45°, such as a range of 0° to 40°, a range of 5° to 40°,a range of 10° to 35°, a range of 10° to 30°, or a range of 20° to 30°.

In another embodiment illustrated in FIG. 24, FIG. 25, FIG. 26, FIG. 27,FIG. 28, and FIG. 29, a handle 2400 includes a handle body 2402 an upperattachment point 2404 for attaching to a rail mounting system. The body2402 includes contact surfaces for the palm of the hand 2406, 2408, or2416. One or more of the contact surfaces can be stippled, ribbed, ortextured. The body 2402 can include an index finger contact surface 2412separated from the palm contact surfaces 2406, 2408, and 2416 by a ridge2414. Upper contact surfaces 2420 can be provided to contact the tip offingers or the padding at the base of the thumb. Further, the body 2402can include a contact surface 2410 to engage the side of the hand. Inaddition, the body 2402 can define a thumb rest 2418 that has a lowersurface 2426 and a front upward extending surface 2424. One or more ofthe contact surfaces can be stippled, ribbed, or textured. For example,as illustrated, contact surfaces 2406 and 2420 can be stippled, ribbed,or textured.

As illustrated in FIG. 24 and FIG. 25, the body 2402 can define openingsfor buttons 2442 and 2444 to provide functionality and control ofauxiliary devices disposed or attached to a powered rail system. Forexample, the button 2444 can be a mode select button, allowing theselection of individual rails or the selection of an individual railalong with a desired power configuration or waveform. Once a mode isselected, the activation button 2442 can be applied to implement theselected mode.

While not illustrated, one or more signaling mechanisms can be utilizedto indicate which mode is selected. For example, one or more LEDs can bedisposed on the backside of the handle. Alternatively, a vibrationalsignal can be used. In another example, a sonic signal can be used toindicate the mode. In a particular configuration including an orderedset of modes, a single LED disposed at the back of the handle can blinka number of times to indicate which mode is selected. In anotherexample, the handle can vibrate upon selection of the mode to indicatewhich mode is selected. In a further example, when a particular mode isselected, a sonic signal, such as an alarm, can sound from within thehandle.

The handle can also include a multi-pin front interface 2430, such as awired interface, to interact with a head device having multiple lightsources or other attached devices. In a particular example, themulti-pin interface 2430 can be waterproof or water tight.Alternatively, the handle can be configured with an attachment point toor can be integrated with a structural extension to couple with a headdevice. In a particular example, the handle, extension, and head can beformed as a unitary piece, or in one or more sections.

FIG. 28 illustrates a rear surface of the handle 2400. The rear surfaceshows an opening 2428 into which a power supply can be disposed. Theopening or cavity 2428 can be isolated using a waterproof backing to beapplied over the backside of the handle 2400. In addition, a rearelectronic interface 2426 can be used to provide power or recharge thepower supply and optionally program modes selectable using the modeselect button 2444. The interface 2426 can be a simple wire interfacefor providing power. In another example, the electronic interface is acommunication interface, such as a serial or parallel interface forproviding programming or power. In an example, the interface 2426 can bea USB interface. In a particular example, the interface 2426 is waterproof.

In particular, the location of the buttons and the contact surfaces ofthe handle can provide for binary mechanical action. Such binarymechanical action leads a user to disassociate actions by a forward handfrom actions of the trigger hand and particularly the trigger finger,preventing accidental discharge of the weapon in stressful situations.In a particular example, a user twists the forward hand at least 10°(e.g., at least)15°, but generally not greater than 60°, from a gripposition to access the buttons.

FIGS. 34-42 includes an illustration of an alternative example of thehandle 3400. For example, the handle 3400 includes a handle body 3402with an interface 3404 to a rail system. The handle 3400 also includesgrip contact surfaces 3414 for hands. In addition, the handle 3400includes an adjustable index finger insert 3412 insertable into anopening 3424 in the handle body 3402. The position of the index fingerinsert 3412 can be adjusted within the opening 3424 to suit a user'sgrip. In another example, the handle body 3402 can include openings 3410to receive a thumb paddle 3406. The thumb paddle 3406 can include aguide 3408 to guide the paddle 3406 into position within thumb paddleopenings 3410. As illustrated, the handle body 3402 includes thumbpaddle openings 3410 on both sides of the body permitting positioning ofthe thumb paddle 3406 on the side of the handle body 3402 depending uponthe handedness of a user or permitting thumb paddles on both sides ofthe body. In a particular example illustrated in FIG. 36, the thumbpaddle 3406 can be positioned at different positions within the thumbpaddle opening 3410 based on the location of pin holes 3626. The thumbpaddle 3406 can be inserted into the opening 3410 to position a holeextending through the thumb paddle 3406 in alignment with the pin hole3626 and a rod or post can be inserted through the thumb paddle 3406 andthe pin hole 3626.

On either side or both, the handle body 3402 can include guideinterfaces 3416 to receive a pressure pad keeper 3418. In the case ofboth sides including the guide interface 3416, an additional panel 3420can be included that does not have pressure pad keeper features.Optionally, a backplate 3422 can be applied to further secure thepressure pad keeper 3418 or panel 3420 within the guide interface 3416.Optionally, the handle body 3402 can be hollow and the backplate 3422can secure items within the hollow body 3402 of the handle 3400. In anexample illustrated in FIG. 38, the pressure pad keeper 3418 includes awindow 3828. A pressure pad can be inserted between the guide interface3416 and the pressure pad keeper 3418 and optionally secured within thepressure pad keeper 3418 using a screw or other mechanism. The pressurepad can be accessible, for example to turn an accessory device on or offthrough the window 3828.

For example, in an alternative example illustrated in FIGS. 43-45, alighting system and handle can be configured to interface without a wireextending between the handle and light source. For example, the handle4300 includes a handle body 4302 with a front interface 4310 and a railinterface 4304. Optionally, the system includes a rear communicationsinterface 4312 and includes buttons, such as a mode select button 4306and an activation button 4308. The front interface 4310 of the handlebody 4302 can both mechanically and electronically interface with thehead 4502 as illustrated in FIG. 45. The interface 4506 includes bothmechanical and communications interfaces to the handle. As illustratedin FIG. 44, a clip includes a front portion 4402 to engage a top side4504 of the head 4502 and includes a rail interface 4404 to engage arail system. When assembled, as illustrated in FIG. 46, the system 4600includes a firearm 4602 and the handle 4604 connected directly to a head4606 and to a rail system.

In a further exemplary embodiment illustrated in FIG. 50, FIG. 51, andFIG. 52, a handle 5000 includes a body 5002 coupled to or integratedwith an interface 5004. The interface 5004 can engage a handguard orforestock of the firearm, for example, a rail mounting system, such as aPicatinny rail mounting system, KeyMod™ system, another rail mountingsystem, or any combination thereof. The body 5002 can further define agrip post 5012 extending downward and rearward relative to the interface5004.

One or more thumb paddles 5006 can extend from sides of the body 5002.In an example, thumb paddles 5006 can include posts that engage openings5022 within the body 5002. For example, a thumb paddle 5006 canselectively engage an opening 5002 at one or more positions along thebody 5002. The handle 5000 can include a single thumb paddle 5006 or, asillustrated, can include two thumb paddles 5006 extending from oppositesides of the body 5002. In a further example, the thumb paddle 5006 canbe rotatable, for example, along an axis of the post that engages theopenings 5022.

The body 5002 can further define an index finger grip surface 5008. Theindex finger grip surface 5008 can optionally be movable between one ormore select positions. The index finger grip surface 5008 can beseparated by a ridge 5010 from the rearward and downward extending grippost 5012.

The grip post 5012 can include a lower grip surface 5014 and one or moreupper grip surfaces 5016 to engage the palm or one or more additionalfingers of the hand. The grip post 5012 can include a barrier structure5020 extending downward from a distal end of the grip post 5012. Thebarrier structure 5020 can engage the rearward surface of a fingerengaging the grip post 5012.

The handle 5000 can include electronic interfaces, such as buttons,activators, or pressure pads. In an example, the electronic interfacescan be disposed on a top surface of the grip post 5012. As illustrated,a pressure pad activator 5018 is disposed on the top surface of the grippost 5012. Alternatively, one or more buttons, such as mode select oractivator buttons can be disposed on the top surface of the grip post5012. Further, the grip post 5012 includes an opening to receiveelectronics or other tools and devices. The opening can be secured orclosed using an end cap or cover plate 5224.

An exemplary thumb paddle is illustrated in FIG. 53 and FIG. 54. Thethumb paddle can include a main body 5302 to receive a thumb and caninclude a post 5304. A top surface 5308 of the body 5302 can beconfigured to receive a thumb and can be concave. A forward ridge 5312optionally extends higher than the surface 5308. Proximal to the post5304, a ridge 5316 can restrict movement of the thumb towards the bodyof the handle. At an edge distal form the post, a ridge 5314 can guidethe thumb to remain in position on the surface 5308. The thumb paddlebody 5302 can also include an under side 5310 that is flat or convex.The post 5304 can include an interface, such as an opening to receive apin, to secure the thumb paddle to the handle.

In an exemplary embodiment, the index finger grip can be adjustable toextend outward from the body or be drawn into the body of the handle,depending upon the user's preference. In an example, an insert 5502 candefine a front surface 5504 to receive an index finger. One or morepositioning posts 5506 or 5508 can extend into the body of the handleand can be secured in place at selective positions based on openings5510 to receive a locking bolt, pin or screw.

An exemplary cover plate 5602 to cover a distal end of the grip post isillustrated in FIG. 56 and FIG. 57. In an example, the cover plate 5602includes a front surface 5604 and a slot 5606 to receive wires ofelectronics, such as a pressure pad. As illustrated in FIG. 57, thecover plate 5602 can include a recess 5708 and can include structures5710 to engage a pressure pad activator.

As illustrated in FIG. 58 and FIG. 59, a pressure pad activator 5802includes structures such as posts 5804 to align the pressure padactivator, as well as a front ridge 5810 to engage the handle and a backridge 5812 to engage the cover plate. Optionally, structures 5804 can beformed of resilient material or can include springs. The activator 5802can include a pinch structure 5806 to apply pressure to the pressure padwhen pressure is applied downward from a top surface of the pressure padactuator 5802.

In use, the handle or grip permits positioning of the thumb, indexfinger, and remaining fingers at positions advantageous for controllingand manipulating a firearm. In particular, the thumb can be positionedapproximately parallel with the barrel and positioned under or below thebarrel in relative height. Further, the positioning of the thumb paddlein relation to the handguard places the thumb in a recess definedbetween the thumb paddle and a lower surface of the handguard or railsystem. Such positioning of the thumb provides advantageous protectionfor the thumb and further control of the barrel position. Thepositioning of the index finger and the remaining fingers of the handallow the arm to be in an approximately neutral, although partiallysupinated position. Together, the grip permits a greater range of motionleft and right when aiming the firearm, better control of the firearmusing the less dominant hand, and manipulation of the firearm using theless dominant hand without maintaining contact with the more dominanthand. In particular, the three points of compression in the describedconfiguration proves control of dragging weight and barrel curl and isparticularly useful for controlling muzzle rise of the firearm when inuse by a weaker individual or child. As such, the handle or gripprovides for greater safety. Further, the less dominant hand can rotatethe weapon and provide control of the weapon during a dominant handmagazine change. Embodiments including adjustable or rotatable thumbpaddles provide for improved handling of the weapon at different firingspeeds. Further, control by the less dominant hand can free the moredominant hand during hand-to-hand combat or allow quick switchingbetween lethal and nonlethal force when approach by an assailant. Thelow-profile of the handle along the sides provides less loss ofperipheral vision, fewer blind spots and limits the risk of the handlecatching on a corner or an article of clothing or strap.

The handle, when connected to a powered rail system, can controlauxiliary devices attached to a powered rail or optionally to a controlrail. For example, as illustrated in FIG. 30, an exemplary auxiliarydevice 3000 can be coupled to a rail of the powered rail mounting systemand can be controlled using the handle. Exemplary auxiliary devicesinclude visible light sources, infrared light sources, laser sources,cameras, Tasers, or any combination thereof. In the illustratedauxiliary device 3000, a device body 3002 includes a power circuitry3004. The circuitry 3004 can be utilized to control the auxiliary device3000, such as to control a light source 3006. In an example, the body3002 is coupled to a rail interface 3016 allowing the device 3000 to becoupled to a rail of the rail mounting system. In an example, the railinterface 3016 includes pins 3018 extending from a side of the openingof the interface 3016 attached to the rail mounting system. The pins3018 can engage access points disposed along sides of a powered rail.The pins 3018 can provide power to the circuitry 3004 and control theoperation of the light source 3006.

In an alternative example, an interface 3008 can interface with aseparate rail attachment interface 3012 that can attach to an accesspoint of the rail. For example, pins 3014 can couple with the accesspoints on the sides of the powered rail to provide power through thewired connection 3010 to the interface 3008 and circuitry 3004.

To modify existing auxiliary devices for use with the rail mountingsystem, an adapter can be provided which replaces power supplies orbatteries of rail mounted auxiliary devices with an adapter that drawspower from the powered rail system. For example, as illustrated in FIG.31, an adapter 3102 imitating a battery can include a central structure3104 having disposed thereon contacts 3106 or 3108 which imitate batterycontacts to electrically couple with an existing auxiliary device. In anexample, a first contact 3106 can be disposed at a front of thestructure 3104. A second contact 3108 can be disposed along thecircumference towards the front or rear depending upon the configurationof the power supply utilized by the existing auxiliary device.Alternatively, both contacts 3106 and 3108 can be disposed at a front,rear or along the side of the auxiliary device depending on theconfiguration of the power supply of the auxiliary device.

In addition, one or more seals 3110 can be disposed along the structure3104 to provide a water-tight seal or to provide spacing between thestructure 3104 and side walls of the cavity of the auxiliary device intowhich the power supply was previously inserted. A rear connector 3112can provide for a tight seal to the back of the auxiliary device andoptionally replace a cap or plates, providing watertight seals to thepower supply compartment of the auxiliary device. In an alternativeexample, a kit can be provided to adapt an existing cap or backplate toreceive the structure 3104 and associated wiring (e.g., wire 3114).

An interface 3116 includes pins to attach to access points of thepowered rail. The pins can provide power through the electrical conduitor wire 3114 to the adapter 3102, which provides power to the auxiliarydevice.

FIG. 48 and FIG. 49 illustrated an alternative example of an accessoryadapter for the powered rail system. For example, as illustrated in FIG.48, a system 4800 includes an accessory 4802, such as a flashlight, thatreceives a modified powercore 4804 that is attached by wire to anelectrical rail interface 4806. In the example illustrated in FIG. 49,an electrical rail interface 4902 includes pins 4906 to electricallycouple the wires 4904 to the powered rail system.

In a particular example, the rail mounting system can be utilized tocontrol a variety of auxiliary devices connected to the rail, a headdevice disposed at a front position of the firearm, or one or moreadditional devices attached to the head device. Controls disposed on thehandle can be utilized to select which devices to activate anddeactivate, as well as provide power to the devices. In an example, thehandle can include control circuitry that is programmable to includedifferent modes in a selectable order.

For example, as illustrated in FIG. 32, a rail mounting system 3200includes a powered rail system 3202, optionally a head device 3204, anda control handle 3206. The control handle 3206 includes an electronicinterface to the powered rail system 3202 and optionally, a separateinterface 3208 to the head device 3204.

In a particular example, the handle 3206 includes a control circuitry3214 and a power supply 3216. The control circuitry 3214 can interfacewith a power supply 3216. Depending upon the mode selected, the controlcircuitry 3214 can provide power through one or more interfaces 3216,3208 or 3220 to control auxiliary devices or head devices. For example,a mode select button 3218 and an activation button 3210 can beelectronically connected to the control circuitry 3214. Activation ofthe mode select button 3218 can permit the control circuitry 3214 totoggle between modes, and selection of the activation button 3210 canresult in implementation of the selected mode through the controlcircuitry 3214, providing power in a particular configuration andwaveform through interfaces 3216 or 3208 to the powered rail 3202 or thehead device 3204, respectively.

In a particular example, the control circuitry 3214 is programmablethrough interface 3220. For example, computational device 3212 canaccess the control circuitry 3214 through the interface 3220 to provideprogramming to the control circuitry 3214. In particular, thecomputational device 3212 can provide a variety of mode configurationsand a programmed order of modes to the control circuitry 3214, as wellas a type of signal to use in signaling the transition between modes,such as using lights, vibration, or sound. In another example, thecomputational circuitry 3212 can access the control circuitry 3214 toaccess data stored with the control circuitry 3214 or on auxiliarydevices. For example, a camera mounted to the powered rail system 3202or the head device 3204 can provide picture or video data through thecontrol circuitry 3214 to the computational circuitry 3212 via theinterface 3220.

Alternatively or in addition, the handle 3206 can include a wirelesscommunication circuitry 3224 in communication with the control circuitry3214. The wireless communication circuitry 3224 can provide for wirelesscommunication with the computational device 3212 or other devices. In anexample, the wireless communication circuitry 3224 can be configured tocommunicate over telecommunications bands in accord with acommunications protocol or based on a proprietary protocol. For example,the communication circuitry 3224 can be configured to interact with802.11x compliant networks. In particular, the communication circuitry3224 can access BluetoothTM or Wi-Fi networks. In an additional example,the communication circuitry can communicate with GPS systems, satelliteuplinks, cellular networks, or other communications systems. In aparticular example, the communication circuitry 3224 can communicatewith devices associated with the head device 3204.

Optionally, power can be provided through the interface 3220 either fromor to the power supply 3216 via the control circuitry 3214. For example,an external power source can be used to recharge the power supply 3216through the interface 3220. In an alternative example, an externaldevice can be powered by the power supply 3216 utilizing the controlcircuitry 3214 and the interface 3220. For example, a handheld device,such as a mobile phone, mobile radio, GPS locators, or camera, canoptionally be powered from the power supply 3216.

The control circuitry 3214 can further provide a signal indicating alevel of power available in the power supply 3216. For example, thecontrol circuitry can illuminate a light emitting diode (LED) in theback of the handle to indicate when power supply is low or providing anindication of the level of power available from the power supply 3216.

For example, as illustrated in FIG. 33, a method 3300 includesconnecting the handle to a computational device, as illustrated at 3302.The computational device can communicate with a control circuitry of thehandle providing power, providing programming, or retrieving data fromthe control circuitry of the handle.

As illustrated at 3304, the computational device can provide modes tothe control circuitry of the handle. For example, the computationaldevice can provide an ordered set of power settings to be utilized bythe control circuitry of the handle in response to application of themode select button. Each power setting can include a powerconfiguration, such as a voltage and waveform, to be provided to aselect rail, as well as optionally providing for a time period overwhich the power settings are to be supplied to the rail. In anotherexample, a power setting included within the ordered set can includepower settings for light sources or devices disposed on the head device.

In addition, the programming can include an indication of how users areto be signal once a select mode is selected. For example, theprogramming can include an indication of LED signals to be displayed tothe user, vibrational settings, or alarms that can be activated inresponse to selection of a particular mode within the ordered set ofpower settings.

As illustrated at 3306, a user can select a mode by activating the modeselect button. Optionally, the control circuitry can notify the user ofthe selected mode and the user can toggle through modes by repeatedlyselecting the mode select button. Once the user has selected a mode, theuser can then activate the select mode, as illustrated at 3308, viaapplication of the activate button. In response to application of theactivate button, the control circuitry can implement the select mode,for example, power can be supplied to a select rail for a select periodof time.

In a first aspect, a mounting system for a firearm is described.
